The actuator (100) further includes a second compensator (106). The second compensator (106) is configured to compensate for a relative misalignment between the linear actuator (102) and the support structure (170).

A resin molded product (10) includes a resin molded product main body (11), and a protrusion (12) integrally formed with the resin molded product main body (11) and protruding from the resin molded product main body (11). At injection molding of the resin molded product (10), molten resin flows through a portion (C-1) corresponding to the protrusion (12) in a cavity (C) defined by a pair of molds (20, 30). A concave portion (14) is formed on a rear side of the protrusion (12), and a bulging portion (12a) having a hollow bag shape is formed on a front side of the protrusion (12).

A seal molding system may include a mold body having a mold inner geometry formed complementary to a fitting outer geometry of a fitting. The mold body may have a mold base formed complementary to a panel surface. The mold body may include an injection hole for injecting sealant into the mold cavity, and a vent hole for venting air and sealant from the mold cavity.

In a plastic injection machine, a controller in electrical communication with a motorized clamp assembly, a heated cylinder barrel, a motorized pre-plasticizing assembly, an injection assembly, and an air mover and that executes an application that configures the controller to: (i) feed thermoplastic material into a heated cylinder barrel that is closed at one end by an injection valve; (ii) warm the heated cylinder barrel to thermoplastic material to a liquid state; (iii) actuate an injection motor to preload a spring biased plunger received within another end of the heated cylinder barrel, thereby pressurizing liquid thermoplastic material in the heating cylinder barrel to an injection pressure set value; (iv) actuate an injection valve motor to open the injection valve causing the pressurized liquid thermoplastic material to inject into a clamped mold; and (v) release a portion of the clamped mold to release the molded article.

A mold for casting a polymeric aircraft window panel includes a first mold half (12) having a first mold surface (24), and a second mold half (14) having a second mold surface (50). The first mold surface (24) and/or the second mold surface (50) have a shape conforming to a final shape for the major surfaces of the aircraft window panel. The first mold half (12) and/or the second mold half (14) can be formed of rolled, hydroformed, or stamped metal.

An automatic opening and closing device for a mold assembly includes a base, a pivot seat, a first extensible unit, an upper mold mounting unit, two shafts, a second extensible unit, a left arm and a right arm. The first extensible unit can move the upper mold mounting unit downward to clamp or release the mold, and the second extensible unit is used to move the pivot seat between two positions. When the pivot seat is in a first position, the upper mold mounting unit can be lowered down to secure or release the mold by the first extensible unit, when in the second position, the upper mold mounting unit and the mold can be rotated an angle, to perform opening or closing of the mold assembly.

An injection molding system includes an injection station, a molding device, and a plunger. The injection station includes a platform including an opening and an injector over the platform. The molding device is disposed between the platform and the injector and over the opening, wherein the molding device includes a mold cavity and a clamping unit for clamping the molding device. The plunger under the platform, wherein the plunger includes a base and a rod extendable through the opening toward the molding device and retractable toward the base. An injection molding method includes conveying a molding device to an injection station and disposing the molding device between an injector and a platform; disposing a plunger under the platform; moving the injector towards the molding device; applying a plunging force on the molding device by extending the rod through the opening; and injecting a molding material into a mold cavity.

The safety device for injection molds comprises: a plate (1) attachable to a fixed part of a mold; a base (4) attachable to a movable part of a mold; wherein the base (4) comprises a safety shaft (10) movable between an unmounted position, wherein said safety shaft (10) is housed in a bore (13) of the plate (1), preventing displacement between the plate (1) and the base (4), and an assembled position, in which said safety shaft (10) is located outside the hole (13) of the plate (1), the displacement of the safety shaft (10) being driven by an actuator (7), allowing displacement between the plate (1) and the base (4). It ensures the connection of the two parts of the mold when the mold is not mounted on the injection molding machine.

An injection molding machine has a clamp that generates electromagnetic force and that secures a moving plate or a fixed plate using attractive force that is produced by the electromagnetic force; and a controller that controls separation force that acts on the moving plate or the fixed plate such that the separation force is less than the attractive force.
